Dublin chief Costello issues warning on football's trial rules

Dublin GAA chief executive John Costello admits he is as apprehensive as he is curious about football's new experimental rules, fearing they may only strengthen the hand of those who "worship at the altar" of the defensive and negative game.

In his always-engaging annual report to Dublin's annual convention next week, Costello says he would have preferred a 13-a-side game to be trialled without any alterations to the playing rules to see if it would alleviate some of the game's defensive gridlock.
